Thanks Both

Just planning ahead a bit...still got to finish the Fus and get it out of
the shed before I have space to start on the wings.

Thanks again

Hi Nigel !

Al is right - just buy another 5 gallons !!! ;-)

....... and just get it flying !!!!! :-)

Header tanks are almost always unnecessary and BAD NEWS !!
I lost a good friend because the header tank under the panel split open,
drenching him - and the hot exhaust manifold - with fuel !!! (Super Cub)
:-(

I've flown all kinds of Murphy aircraft, with all kinds of different
variations on the fuel system, in all kinds of extreme attitudes, and
NEVER had a fuel flow problem !! I can't say that about several
certified aircraft i've flown & owned ....

I have deliberatley run a tank completely dry in flight - by flying
with that wing raised to drain the last drop out. I just leveled the wings,
turned that tank off, and turned on the other side - the engine hadn't
stopped
windmilling, and just picked right up and I flew home & landed. I wanted
the tank dry so I could replace the sight guage tubing, which had been
discoloured by bad gas. If anyone worries about this, just add a fuel valve
from a Renegade to the bottom of the sight guage tubes - these are small
1/8" valves, that will allow you to shut fuel out of the guage in the
event of leaks or discolouration...

Keep rivetting - it IS worth it !!! ;-) :-)

Hi All

I remember a thread a few years ago about fuel starvation with fairly
extreme nose pitch up and down attitudes and lowish fuel contents.

A local Maverick I looked at recently has a small header tank located just
behind the pilots head to prevent this happening. (not sure if this is
standard in a Maverick or not).

Has anyone experienced this problem in a Rebel / Elite, and any thoughts

on

installing a "flop tube" (INVERTED PICKUP TUBE) in each wing, my thoughts
being if fuel contents where low the tube would travel with the fuel and
hopefully remain in it ?

I've never seen one of these flop tubes so it might not be suitable at all
- just wondered ?
